Passing JSON to WCF

Question

User-321479612 posted

I tried passing this json object:

{"AppStart":true,"DateFormat":"YYYY-MM-DD"}

to this service:

[OperationContract]
    [WebInvoke(
      Method = "POST",
      RequestFormat = WebMessageFormat.Json)]
    string SavePreferences(string jsonPreferences);

In this case I always get null for jsonPreferences in my service

Add this after Method ='POST' or RequestFormat-

ResponseFormat = WebMessageFormat.Json

If it still does not work then try to test the service in fiddler.

You can enable some kind of logging that after hitting the method is it failing at some point.

Please, use the below format

[

WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped, UriTemplate = "Your URI Template like for example InsertCustomer/Customer_ID"

)]

string SavePreferences(string jsonPreferences);

thanks so far!! maybe it would be easier if  I should just send it as a stringified JSON to WCF since it will be saved as a string in the DB?
